— NASA's Hubble confirms that galaxies are the ultimate recyclers — New observations by NASA's Hubble Space Telescope are expanding astronomers' understanding of the ways in which galaxies continuously recycle immense volumes of hydrogen gas and heavy…
— Frozen comet had a watery past, University of Arizona scientists find — For the first time, scientists have found convincing evidence for the presence of liquid water in a comet, shattering the current paradigm that comets never get warm enough to melt…
— Sugar-grain sized meteorites rocked the climates of early Earth and Mars — Bombardments of 'micro-meteorites' on Earth and Mars four billion years ago may have caused the planets' climates to cool dramatically, hampering their ability to support life, according…
— Astrophysicist: White dwarfs could be fertile ground for other Earths — Planet hunters have found hundreds of planets outside the solar system in the last decade, though it is unclear whether even one might be habitable. But it could be that the best place…
— Integral spots matter a millisecond from doom — ESA's Integral gamma-ray observatory has spotted extremely hot matter just a millisecond before it plunges into the oblivion of a black hole. But is it really doomed? These unique observations…
— MESSENGER spacecraft to swing into orbit around Mercury — At 8:45 p.m. EDT on March 17, the MESSENGER spacecraft will execute a 15-minute manoeuvre that will place it into orbit around Mercury, making it the first craft ever to do so, and…
— Baby stars born to 'napping' parents — Cardiff University astronomers believe that a young star's long 'napping' could trigger the formation of a second generation of smaller stars and planets orbiting around it…
— Oldest objects in solar system indicate a turbulent beginning — Scientists have found that calcium, aluminium-rich inclusions (CAIs), some of the oldest objects in the solar system, formed far away from our sun and then later fell back into the…
— Oxygen isotope analysis tells of the wandering life of a dust grain 4.5 billion years ago — Scientists have performed a micro-probe analysis of the core and outer layers of a pea-sized piece of a meteorite some 4.57 billion years old to reconstruct the history of its formation,…
ESA pays tribute to 50 years of space
Fifty years ago today, on the night of 4 October, the first 'beep-beep' from Sputnik fell from the heavens and marked the beginning of a new era for the human race.
Satellites and space probes have dramatically changed our way of living, they have turned the world into a global village where an unprecedented wealth of information is at hand anywhere, anytime. The world has shrunk, and our perception of our planet has changed too. Thanks to remote sensing and Earth observation, we can now take the pulse of our environment and devise politics based on an increasing knowledge of the way our world is evolving.
We have explored many worlds in the Solar System and our space-based instruments have been able to open large windows into previously unknown realms of our universe. What was thought to be quiet has revealed its violence and its incredible activity. Men and women have ventured out of their planetary cradle and have succeeded in their first exploration of another world. They have settled in space and started to work there, first in competition, and then as a global cooperation, in a spirit of peace and for the benefit of mankind.
On the ground, engineers, scientists, technicians, but also politicians, and sometimes dreamers, have worked together to make dreams come true, changing our lives for ever, and hopefully for the best.
Europe's contribution to this great adventure has been significant since the very beginning - although sometimes hidden and little known to the general public. Most of the great concepts that led to the development of space technologies and applications were born in Europe, from rocket design to geostationary orbit, and European scientists have been involved in many of the successes of these last five decades.
Halfway into the first century of the human conquest of space, 2007 indeed sees the results of years of investment and daring engineering, both 'made-in-Europe' and in cooperation with the United States and Russia.
Since the beginning of the year, ESA has been looking at the achievements of some of these key actors in space and describing the many advances that have been made in space science and technology, from access to space and Earth observation to the exploration of planets and of the wide universe.
